Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & the risk of death.

You :
You have extremely high blood pressure â€“ a hypertensive crisis is often defined by a systolic blood pressure of 180 or higher or a diastolic blood pressure of 120 or higher. Blood pressure this high can damage blood vessels or lead to a stroke.
With a blood pressure as high as you have reported, you should seek immediate medical attention. Treatment for blood pressure this high may include hospitalization for treatment with intravenous (IV) medications.
I am very concerned that you will not live to be 50 unless you begin to control the risk factors that contribute to your mortality risk â€” smoking, high blood pressure, lack of exercise and alcohol consumption, if it is excessive.

Slowly:
The heart is a muscle, and uses electricity to generate the "squeeze" necessary to get blood to the whole body. Stents keep blood flowing to the muscle, and a pacer/defibrillator keeps the electricity on and timed right. When part of the heart is dead, patients are less active. They also may develop congestive heart failure, with fluid backing up into lungs. Pills can help.
